Porpoises have a blowhole they have to open and close when emerging and submerging in water. Also, when underwater, they're not breathing at all, they're holding their breath.
Porpoises have to consciously breathe. Its not a natural, second nature thing to do like most mammals, due to the fact that they hold their breath and don't constantly breathe in and out like other mammals that live out of the water.
